Quran 39:6

39:6 8 species or pairs clearly stated

6 :142-144 8 species or pairs are specified and 4 are mentioned

Secularly, a modern supermarket supposedly has 47,000 items in it, and if I send you eight of them, does that imply the others do not exist?

Molecular studies have supported monophyly in the family Bovidae (a group of organisms comprises an ancestral species and all their descendants).^[5][6] The number of subfamilies in Bovidae is disputed, with suggestions of as many as ten and as few as two subfamilies.^[6] However, molecular, morphological and fossil evidence indicates the existence of eight distinct subfamilies: Aepycerotinae (consisting of just the impala), Alcelaphinae (bontebok, hartebeest, wildebeest and relatives), Antilopinae (several antelopes, gazelles, and relatives), Bovinae (cattle, buffaloes, bison and other antelopes), Caprinae (goats, sheep, ibex, serows and relatives), Cephalophinae (duikers), Hippotraginae (addax, oryx and relatives) and Reduncinae (reedbuck and kob antelopes). In addition, three extinct subfamilies are known: Hypsodontinae (mid-Miocene), Oiocerinae (Turolian) and the subfamily Tethytraginae, which contains Tethytragus (mid-Miocene).^{[7][8] via wikipedia}

ADW: Bovidae: CLASSIFICATION

In the verse “he sent down for you eight heads of cattle in pairs”, God the almighty has mentioned the creation of man from a single soul and reiterated sending down the “eight heads of cattle in pairs” and spoke of livestock. Attributing the verb “sending down” to “eight heads of cattle in pairs” has led to various viewpoints such as parallelism of the creation in these animals; however, studying the concept and formation of “eight heads of a cattle in pairs” regarding the word count for “eight”, its semantic relationship with the things referred to, the collocating verb and other components of the verse have not been considered yet. This issue makes scrutinizing the semantic implications of the phrase “eight heads of cattle in pairs” more important. Based on this, and by relying on Quranic functions, and by making use of the etymology and symbolism of the words in the above verse such as “eight”, “pairs” and “sending down”, we can infer meanings such as “balance, correspondence, and lawfulness of nature”, “being paired, linking and balance” and “destiny and measuring the creature from the divine treasures” respectively. Also, based on clues such as the register of the verse, the implied meaning of the “balance and lawfulness of the creation in this world” can be inferred for the phrase “eight heads of cattle in pairs”.

Only four / eight types of cattle?

39:6 He created you from a single soul. Then He made from it its mate. And He sent down for you of (mina) the cattle eight kinds. He creates you in the wombs of your mothers, creation after creation, in three darkness[es]. That is Allah your Lord; for Him is the dominion. There is no god except Him. Then how are you turning away?

(The Verse does not say that there are only four / eight types of cattle, but the sentence “for you of/from the cattle” implies that “among/from” all the cattle that exist, eight kinds are “for you”)(Allah knows best)

6:142 And of (wamina) the cattle (are some for) burden and (some for) meat. Eat of what Allah provided you, and do not follow the footsteps of Satan. Indeed, he is to you an open enemy. 6:143 Eight pairs - of the sheep two and of the goats two. Say, "(Are) the two males He has forbidden or the two females or that which the wombs of the two females contain? Inform me with knowledge, if you are truthful." 6:144 And of the camels two and of the cows two. Say, "(Is it) the two males He has forbidden or the two females or that which the wombs of the two females contain? Or were you witnesses when Allah enjoined you with this? Then who is more unjust than (one) who invents a lie against Allah to mislead the people without knowledge? Indeed, Allah does not guide the wrongdoing people."

(According to the context, people wrongly forbade some of the eight kinds of cattle which were allowed (6:144))(The Verses do not say that there are only four / eight types of cattle, but that’s the cattle that is “for you” (39:6, 6:142). Verse 6:142 makes distinction between cattle: some cattle is for burden, and some for meat, or for both)(It is interpreted that the mention of eight kinds of cattle might refer to the only quadruped animals or livestock or farm animals that are for you. The root of “l-an’ami” (the cattle) is N-Ain-M, and it means “soft in the concrete sense. In abstract, it means anything that can be understood as soft as in soft to touch and soft in treatment and soft life as in a life that does not have much hardship”)(Another point is that Verse 7:160 tells about eating quails, so, other than cattle is also allowed for eating. The Verses of the Qur’an are not mutually exclusive but complement each other)(Allah knows best)by amin
